They are active but not super talkative except at certain points during the day. It's not like your old-school railroading where everything is done via radio. For the Windsor/Santa Rosa area I would put in Geyser Peak, Sonoma Mountain, AND Big Rock. Main1 is for S.M.A.R.T. themselves and Main2 is for the freight side right now. MoW is for Maintenance, obviously. "Security" isn't much used as the officers stay on Main1.
